In the article 'How Long is a Piece of Time: Phenomenal Time and Quantum Coherence - Toward a Solution' by Professor Ram Vimal and Myself, the problem of phenomenal time was addressed in an original way by asking the question 'What bio-metric associated with brain function determines the apparent 'rate' at which time is experienced?'.
The analysis provided strong evidence supporting the idea that the neural correlate of consciousness is a macroscopic coherent wave function - perhaps similar to a Bose-Einstein condensate.
Furthermore, the analysis suggests that the wave function comprises an underlying solitonic 'carrier wave' with an associated uncertainty in time (Delta 't') of around 16th-18th of a second.
The Fractal Catalytic Model does not look to quantum coherence as a computational advantage, but rather, as a unique ontology distinct from the classical. Thus, the wave function is understood to be both a continuous mathematical/relational and at the same time 'conscious' solution to a set of boundary conditions.
I would hazard that, given the size of the uncertainty in time (Delta 't') and the fact we know its' value, we should be able to devise some method of observing it or detecting its presence in some way.
